PVG 32 with open center PVP (fixed displ. pump) • PVB with flow control spool

When the pump is started and the main spools in the individual basic modules (11) are in the neutralposition, oil flows from the pump, through connection P, across the pressure adjustment spool (6) totank. The oil flow led across the pressure adjustment spool determines the pump pressure (stand-bypressure).

When one or more of the main spools are actuated, the highest load pressure is fed through the shuttlevalve circuit (10) to the spring chamber behind the pressure adjustment spool (6), and completely orpartially closes the connection to tank to maintain pump pressure.

Pump pressure is applied to the right-hand side of the pressure adjustment spool (6).

The pressure relief valve (1) will open should the load pressure exceed the set value, diverting pump flowback to tank.

In a pressure-compensated basic module the compensator (14) maintains a constant pressure dropacross the main spool – both when the load changes and when a module with a higher load pressure isactuated.

With a non pressure-compensated basic module incorporating a load drop check valve (18) in channel P,the check valve prevents return oil flow.

The basic module can be supplied without the load drop check valve in channel P for functions with over-center valves.

The shock valves PVLP (13) with fixed setting and the suction valves PVLA (17) on ports A and B are usedfor the protection of the individual working function against overload and/or cavitation.

An adjustable LS pressure limiting valve (12) can be built into the A and B ports of pressure-compensatedbasic modules to limit the pressure from the individual working functions.

Please see the sectional drawing below for better understanding of this example.

The LS pressure limiting valves save energy compared with the shock valves PVLP:

• with PVLP all the oil flow to the working function will be led across the combined shock and suctionvalves to tank if the pressure exceeds the fixed setting.

• with LS pressure limiting valves an oil flow of about 2 l/min [0.5 US gal/min] will be led across the LSpressure limiting valve to tank if the pressure exceeds the valve setting.

PVG 32 with closed center PVP (variable displ. pump) • PVB with flow control spool

In the closed center version of PVP an orifice (5) and a plug (7) have been fitted instead of the plug (4).

This means that the pressure adjustment spool (6) will only open to tank when the pressure in channel Pexceeds the set value of the pressure relief valve (1).

In load sensing systems the load pressure is led to the pump control via the LS connection (8).

In the neutral position the pump load sense control sets the displacement so that leakage in the system iscompensated, to maintain the set stand-by pressure.

When a main spool is actuated the pump load sense control will adjust the displacement so that the setdifferential pressure (margin) between P and LS is maintained.

The pressure relief valve (1) in PVP should be set at a pressure of approx. 30 bar [435 psi] above maximumsystem pressure (set on the pump or external pressure relief valve).

Load sensing for variable displ. pump supply

The pump receives fluid directly from the reservoir through the inlet line. A screen in the inlet lineprotects the pump from large contaminants.

The pump outlet feeds directional control valves such as PVG-32, hydraulic integrated circuits (HIC), andother types of control valves.

The PVG valve directs and controls pump flow to cylinders, motors and other work functions. A heatexchanger cools the fluid returning from the valve. A filter cleans the fluid before it returns to thereservoir.

Flow in the circuit determines the speed of the actuators. The position of the PVG valve spool determinesthe flow demand. A hydraulic pressure signal (LS signal) communicates demand to the pump control.

The pump control monitors the pressure differential between pump outlet and the LS signal, andregulates servo pressure to control the swashplate angle. Swashplate angle determines pump flow.

Actuator load determines system pressure. The pump control monitors system pressure and will decreasethe swashplate angle to reduce flow if system pressure reaches the pump control setting.

A secondary system relief valve in the PVG valve acts as a back-up to control system pressure.

All makes and all types of control valves (incl. proportional valves) can fail, thus the necessary protectionagainst the serious consequences of function failure should always be built into the system. For eachapplication an assessment should be made for the consequences of pressure failure and uncontrolled orblocked movements.

To determine the degree of protection that is required to be built into the application, system tools suchan FMEA (Failure Mode and Effect Analysis) and Hazard and Risk Analysis can be used.

FMEA – IEC EN 61508

FMEA (Failure Mode and Effect Analysis) is a tool used for analyzing potential risks. This analyticaltechnique is utilized to define, identify, and prioritize the elimination or reduction of known and/orpotential failures from a given system before it is released for production. Please refer to IEC FMEAStandard 61508.

Hazard and Risk Analysis ISO 12100-1 / 14121

This analysis is a tool used in new applications as it will indicate whether there are special safetyconsiderations to be met according to the machine directives EN 13849. Dependent on the determinedlevels conformity this analysis will detirmine if any extra requirements for the product design,development process, production process or maintenance, i.e. the complete product life cycle.

W WarningAll makes/brands and types of directional control valves – inclusive proportional valves – can fail andcause serious damage. It is therefore important to analyze all aspects of the application. Because the proportional valves are used in many different operation conditions and applications,the manufacturer of the application is alone responsible for making the final selection of the products – and assuring that all performance, safety and warning requirements of the application are met. The process of choosing the control system – and safety levels – is governed by the machine directivesEN 13849 (Safety related requirements for control systems).

Load sensing controls

The LS control matches system requirements for both pressure and flow in the circuit regardless of theworking pressure. Used with a closed center control valve, the pump remains in low-pressure standbymode with zero flow until the valve is opened. The LS setting determines standby pressure.

Load sensing circuit

P101 967

Most load sensing systems use parallel, closed center, control valves with special porting that allows thehighest work function pressure (LS signal) to feed back to the LS control.

Margin pressure is the difference between system pressure and the LS signal pressure. The LS controlmonitors margin pressure to read system demand. A drop in margin pressure means the system needsmore flow. A rise in margin pressure tells the LS control to decrease flow.

LS control with bleed orifice (do not use with PVG valves)

The load sense signal line requires a bleed orifice to prevent high-pressure lockup of the pump control.Most load-sensing control valves include this orifice. An optional internal bleed orifice is available, for usewith control valves that do not internally bleed the LS signal to tank.

Integral PC function

The LS control also performs as a PC control, decreasing pump flow when system pressure reaches the PCsetting. The pressure compensating function has priority over the load sensing function.

For additional system protection, install a relief valve in the pump outlet line.

Load sensing system characteristics:

• Variable pressure and flow

• Low pressure standby mode when flow is not needed

• System flow adjusted to meet system requirements

• Lower torque requirements during engine start-up

• Single pump can supply flow and regulate pressure for multiple circuits

• Quick response to system flow and pressure requirements

Remote pressure compensated controls

The remote PC control is a two-stage control that allows multiple PC settings. Remote PC controls arecommonly used in applications requiring low and high pressure PC operation.

Closed center circuit with remote PC

P101 966

The remote PC control uses a pilot line connected to an external hydraulic valve. The external valvechanges pressure in the pilot line, causing the PC control to operate at a lower pressure. When the pilotline is vented to reservoir, the pump maintains pressure at the load sense setting.

When pilot flow is blocked, the pump maintains pressure at the PC setting. An on-off solenoid valve canbe used in the pilot line to create a low-pressure standby mode. A proportional solenoid valve, coupledwith a microprocessor control, can produce an infinite range of operating pressures between the lowpressure standby setting and the PC setting.

Size the external valve and plumbing for a pilot flow of 3.8 l/min [1 US gal/min]. For additional systemprotection, install a relief valve in the pump outlet line.

Remote pressure compensated system characteristics:

• Constant pressure and variable flow

• High or low pressure standby mode when flow is not needed

• System flow adjusts to meet system requirements

• Single pump can provide flow to multiple work functions

• Quick response to system flow and pressure requirements

Typical applications for remote pressure compensated systems:

• Modulating fan drives

• Anti-stall control with engine speed feedback

• Front wheel assist

• Road rollers

• Combine harvesters

• Wood chippers

PVG 32 main spool with pressure compensated control

The PC control maintains constant system pressure in the hydraulic circuit by varying the output flow ofthe pump. Used with a closed center control valve, the pump remains in high pressure standby mode atthe PC setting with zero flow until the function is actuated.

Once the closed center valve is opened, the PC control senses the immediate drop in system pressureand increases pump flow by increasing the swashplate angle.

The pump continues to increase flow until system pressure reaches the PC setting.

If system pressure exceeds the PC setting, the PC control reduces the swashplate angle to maintainsystem pressure by reducing flow. The PC control continues to monitor system pressure and changesswashplate angle to match the output flow with the work function pressure requirements.

If the demand for flow exceeds the capacity of the pump, the PC control directs the pump to maximumdisplacement. In this condition, actual system pressure depends on the actuator load.

For additional system protection, install a relief valve in the pump outlet line.

C CautionDo not use the PVG 32 with LB control.

PVPC adapter for external pilot oil supply

PVPC with check valve for open center PVP

PVPC with check valve is used in systems where it is necessary to operate the PVG 32 valve by means ofthe electrical remote control without pump flow. When the external solenoid valve is opened, oil fromthe pressure side of the cylinder is fed via the PVPC through the pressure reducing valve to act as thepilot supply for the electrical actuators. This means that a load can be lowered by means of the remotecontrol lever without starting the pump.

The built-in check valve prevents the oil from flowing via the pressure adjustment spool to tank. With thepump functioning normally the external solenoid valve is closed to ensure that the load is not lowereddue to the pilot supply oil flow requirement of approximately 1 l/min [0.25 US gal/min]. With closedcenter PVP the external pilot oil supply can be connected to the pressure gauge connection without theuse of a PVPC plug.

PVPC without check valve for open or closed center PVP

PVPC without check valve is used in systems where it is necessary to supply the PVG 32 valve with oilfrom a manually operated emergency pump without directing oil flow to the pilot oil supply (oilconsumption about 0.5 l/min) [0.13 US gal/min].

When the main pump is working normally, the oil is directed through the PVPC plug via the pressurereduction valve to the electrical actuators.

When the main pump flow fails, the external shuttle valve ensures that the oil flow from the manuallyoperated emergency pump is used to pilot open the over center valve and lower the load. The load canonly be lowered using the mechanical operating lever of the PVG 32 valve.

PVMR, friction detent

The friction detent PVMR allows the directionalspool to be held in any position, resulting ininfinitely variable, reversible, pressurecompensated flow.

This can be sustained indefinitely without havingto continue to hold the mechanical lever.

Friction detent spool position may be affected byhigh differential actuator flow forces and systemvibration resulting in work function flow reduction.

PVBS, main spools for flow control (standard)

When using standard flow control spools, the pump pressure is determined by the highest load pressure.This is done either via the pressure adjustment spool in open center PVP (fixed displacement pumps) orvia the pump control (variable displacement pumps).

In this way the pump pressure will always correspond to the load pressure plus the stand-by pressure ofthe pressure adjustment spool or the pump control. This will normally give optimum and stableadjustment of the oil flow.

PVBS, main spools for flow control (linear characteristic)

PVBS main spools with linear characteristic have less dead band than standard spools and a proportionalratio between control signal and oil flow in the range beyond the dead band. PVBS with linearcharacteristic must never be used together with PVEM electrical actuators.

The interaction between the small dead band of the spools and the hysteresis of the PVEM actuator of20% involves a risk of building up a LS pressure in neutral position.

In a few systems load sensing pump pressure may result in unstable adjustment of the oil flow and atendency towards system hunting.

This may be the case with working functions that have a large moment of inertia or over-center valves. Insuch systems main spools for pressure control can be advantageous.

PVBS, main spools for pressure control

The spools are designed in such a way that the pump pressure is controlled by the spool travel. The mainspool must be displaced until the pump pressure just exceeds the load pressure before the workingfunction is applied. If the main spool is held in this position, the pump pressure will remain constant –even if the load pressure changes – giving a stable system.

The use of pressure control spools, however, also means that:

• the oil flow is load dependent

• the dead band is load dependent

• the pump pressure can exceed the load pressure by more than is usual

• the pressure drop across main spool varies (energy consumption)

Due to these factors it is recommended that pressure control spools are only used when it is known forcertain that problems with stability will arise or already have arisen, and in applications where constantpressure is needed e.g. drill holding.

Background

Instability in load sense control systems in certain applications with oscillations in the range of 1/2 - 2 Hzcan cause severe instability problems while trying to control functions in an application.

Critical applications are usually related to functions with an important inertia torque and/or functionswith secondarily fitted pressure controlled components e.g. over-center valves.

Examples:

• a slewing function• main lifting/lowering function of a crane

The problem usually manifests itself in prolonged oscillation phenomena (Fig. 1), in a relatively constantsequence of oscillations (Fig. 2) or in the worst case in an amplified sequence of oscillations (Fig. 3).

Principle

The idea was to create a system operating independently of a constantly changing load pressure.Therefore, we changed the well-known LS principle (Fig. 4), so that compensated pump pressure is partof the LS system (Fig. 5) after the pressure compensator and before the metering range of the main spool.Upon actuation of the spool, it will be led via a fixed and a variable orifice.

Fig. 4 Flow controlled spool

B

A

P005 625

Fig. 5 Pressure controlled spool

B

A

P005 626

The opening area of the variable orifice is atmaximum at initial actuation and 0 at full stroke ofthe spool and then the pressure created betweenthe two orifices is led into the LS system in theusual way.

In this way the pump pressure is built updepending on the spool travel, i.e. the spool willthen have to be stroked to a position that thepump pressure is higher than the actual loadpressure to make the oil flow from PA/B. Whenthe load changes for a fixed spool position the flowto for the function will also change.

The valve section is now a load-dependent valve,but ensuring a constant pump pressure which isimportant in obtaining a stable function.

Pump pressure vs. spool travel curve

Application

Pressure controlled spools should in principle only be used when you have stability issues. Typicalapplications on a crane:

• Lifting/lowering movement

• Slewing movement with cylinders

• For the main lifting/lowering function on a crane it is recommended to fit a "half" pressure controlspool. This means that the spool is designed with a normal flow control on the lifting port andpressure control connected to the port where the pilot signal to the over-center valve is acting. Youwill thus maintain a load-independent lifting movement and achieve a stable but load-dependinglowering movement.

• As the load pressure on slewing movements is usually steady - irrespective of the crane being loadedor not – it will be advantageous to use a "full" pressure control spool for A and B port.

In both cases we recommend the use of a basic valve, PVB, with pressure compensator. The pressurecompensator will ensure the individual load-independency between the basic valves.

It is further recommended to use the LS pressure relief valves as not only will they ensure individualpressure limitation but also make it possible to adjust the maximum oil flow to the function.

It is not recommended to use shock valves as pressure limiting valves in connection with pressure controlspools.

Sizing

The size of "half" (e.g: P - A = flow control P - B pressure control) pressure control spools is determined onbasis of max. flow demand on the lifting port. If e.g. a max. pressure compensated flow of 65 l/min for thelifting movement, you choose a 65 L/min spool (size D). The metering characteristic has then a given size.As it is often requested to limit the use of the crane boom for downward push/force mode and the LSpressure limitation can be used. It will appear from the characteristics enclosed what effect a pressurelimitation, PLS will have on max. flow on the lowering port.

The size for a "full" pressure control spool is determined on basis of known load pressure, PLS max, andrequested max. flow.

It will appear from the characteristics enclosed that if the load PLS is low and the pump pressure, Pp, ishigh as a result of max. stroked spool you will get a large flow.

If PLS is approaching PLS max. the flow will be reduced and the dead band increased. Max. oil flow can bereduced by approx. 50% without limiting max. pressure.

The reduction is made by limiting the spool travel from 7 mm to 5.5 mm.

Limitation

If a pressure controlled spool is chosen for stability reasons consideration should be made to featuresrelated to the pressure control principle.

Deadband will change according to the load conditions and the valve section will become load-dependent and that the pump pressure may exceed the load pressure.

With all of the above in mind, a “pressure controlled spool” will minimize oscillation and obtain a stablefunction that can be controlled smooth and precise.

PVPX, electrical LS unloading valve

PVPX is a solenoid LS unloading valve. PVPX is fitted into the pump side module enabling a connection tobe made between the LS and the tank lines. Thus the LS signal can be relieved to tank by means of anelectric signal.

For a PVP pump side module in open center version the relief to tank of the LS signal means that thepressure in the system is reduced to the sum of the tank port pressure plus the neutral flow pressure forthe pump side module.

For a PVP pump side module in closed center version the relief to tank of the LS signal means that thepressure is reduced to the sum of the tank port pressure for the pump side module plus the stand-bypressure of the pump.

Electrical control of PVG

Valve actuation with electrical actuators has been supported by Danfoss for a long time. The actuationcan be controlled directly by joystick, by a PLUS+1® controller or by a broad range of third partcontrollers. The actuator controls the spool by building up pilot oil pressure on the end of the spool. Forthe PVE a pilot oil pressure between 10 and 15 bar is used.

Oil

The main duty of the oil in a hydraulic system is to transfer energy. It must also lubricate the moving partsin hydraulic components, protect them against corrosion, and transport dirt particles and heat out of thesystem. It is therefore important to choose the correct oil with the correct additives. This gives normaloperation and long working life.

Mineral oil

For systems with PVG 32 valves Danfoss recommends the use of mineral-based hydraulic oil containingadditives: Type HLP (DIN 51524) or HM (ISO 6743/4).

Non-flammable fluids

Phosphate-esters (HFDR fluids) can be used without special precautions. However, dynamic seals must bereplaced with FPM (Viton) seals. Please contact the Danfoss Sales Organization if the PVG 32 valve is to beused with phosphate-esters.

The following fluids should only be used according to agreement with the Danfoss Sales Organizationfor:

• Water-glycol mixtures (HFC fluids)• Water-oil emulsions (HFB fluids)• Oil-water emulsions (HFAE fluids)

Particle content, degree of contamination

Biodegradable oils

PVG 32 valves can be used in systems with rapeseed oil. The use of rapeseed oil is conditioned by:

• complying with the demands on viscosity, water content, temperature and filtering etc. (see chaptersbelow and technical data).

• adapting the operating conditions to the directions of the oil supplier.

Before using other biodegradable fluids, please consult the Danfoss organization. Oil filtration mustprevent particle content from exceeding an acceptable level, i.e., an acceptable degree of contamination.

Maximum contamination for PVG 32 is 23/19/16 (see ISO 4406. Calibration in accordance with the ACFTDmethod). In our experience a degree of contamination of 23/19/16 can be maintained by using a filterfineness as described in the next section.

For more information, please see the Danfoss literature:

• Design Guidelines for Hydraulic Fluid Cleanliness Technical Information, 520L0467• Hydraulic Fluids and Lubricants Technical Information, 521L0463• Experience with Biodegradable Hydraulic Fluids Technical Information, 521L0465.

Filtration

Effective filtration is the most important precondition in ensuring that a hydraulic system performsreliably and has a long working life. Filter manufacturers issue instructions and recommendations. It isadvisable to follow these.

System filters

Where demands on safety and reliability are very high a pressure filter with bypass and indicator isrecommended. Experience shows that a 10 µm nominal filter (or finer) or a 20 µm absolute filter (or finer)is suitable. It is our experience that a return filter is adequate in a purely mechanically operated valve

system. The fineness of a pressure filter must be selected as described by the filter manufacturer so that aparticle level of 23/19/16 is not exceeded. The filter must be fitted with pressure gauge or dirt indicator tomake it possible to check the condition of the filter. In systems with differential cylinders or accumulatorsthe return filter must be sized to suit the max. return oil flow. Pressure filters must be fitted to suit max.pump oil flow.

Internal filters

The filters built into PVG 32 are not intended to filter the system but to protect important componentsagainst large particles. Such particles can appear in the system as a result of pump damage, hose fracture,use of quick-couplings, filter damage, starting up, contamination, etc. The filter in the electrical actuatorPVE protecting the solenoid valves has a mesh of 150 µm. Bursting pressure drop for internal filters is 25bar [360 psi].

The angle of the handle is determined by which side of the handle that is mount towards the base. If a22.5° angle is needed the "dot" on the handle is not visible. If 37.5° is needed the dot should be visible.

Surface treatment

The PVG valve has as standard, an untreated surface. In certain applications, depend on different factors,such as: salty environment, large temperature changes, high humidity, rust can develope on the surface.This will not affect the performance of the PVG valve group. To prevent/reduce rust development,Danfoss recommend the PVG valve group to be painted. Rust on the surface is not seen as a validcomplaint issue, neither on painted or unpainted PVG valve groups.

An order form for PVG 32 hydraulic valve is shown on the next page.

The form can be obtained from the Danfoss Sales Organization.

Both the module selection chart on the previous pages and the order form are divided into fields 0,1-1-12, 13, 14, 15, a, b, and c.

Each module has its own field:

0:

• Pump side module PVP

• Plug for external pilot oil supply PVPC

• Electrical LS unloading valve PVPX

1-12: Basic valves PVB

13: Main spool PVBS

a: Mechanical actuator PVM (or PVE when option mounted)

c:

• Cover for mechanical actuation PVMD

• Cover for hydraulic actuation PVH

• Electrical actuators PVE (or PVM when option mounted)

b:

• Shock and suction valve PVLP

• Suction valve PVLA

14: End plate PVS

15: Assembly kit PVAS

Please state

• Code numbers of all modules required

• Required setting (P) for pump side module

• Required setting of LSA/B pressure limiting valves, see pressure setting guidance below.

Standard and option assembly

The PVG 32 valve group is assembled the way the module selection chart shows if the code number forPVM is written in field 'a', and the code number for PVMD, PVE or PVH in field 'c'.

The valve group is assembled so that the mechanical actuator is mounted on the opposite end of thebasic module, if the code number for PVM is written in field 'c' of the order form and the code numbersfor PVMD, PVE or PVH in field 'a'.

Reordering

The space at the top right-hand corner of the form is for Danfoss to fill in. The code number for the wholeof the specified valve group (PVG No.) is entered here.

In the event of a repeat order all you have to do is enter the number Danfoss has given on the initialconfirmation of order.

Pressure setting limits

The maximum setting pressure for the pressure limiting valves LSA or LSB depends on the chosenpressure setting for shock valve PVLP. The maximum values recommended to avoid interaction can beread in the following table.

Warnings

Please work through all warnings before implementing actuators in any application. The list of warningsmust not be seen as a full list of potential dangers. Depending on application and use other potentialdangers can occur.

Warnings are listed next to the most relevant section and repeated in a special section at the end oftechnical data. See Product warnings for more information.

W WarningAll brands and all types of directional control valves – including proportional valves – can fail and causeserious damage. It is therefore important to analyze all aspects of the application. Because theproportional valves are used in many different operation conditions and applications, the machinebuilder/ system integrator alone is responsible for making the final selection of the products – andassuring that all performance, safety and warning requirements of the application are met.

Overview

The PVG is a sectional spool valve stack with up to 12 individually controlled proportional valves. The PVGwith the PVE can be operated as single valves or several valves in cooperation. The oil flow out of thework section (A- or B-port) can be controlled by a combination of the following:

• PVE controlling the spool position using pilot oil pressure.

• A handle (PVM) in mechanical interface with the spool.

PVG functionality

The PVG valve distributes oil from pump flow to a particular work function in the application via a specificvalve section. This is done by moving the spool (PVBS).

Depending on the choice of components the oil work flow enters the PVG through the PVP (proportionalvalve pump side module), a PVSK, a mid inlet or other system interface and enters the PVB (proportionalvalve basic module) via the P gallery and leaves through the T gallery.

The PVP/PVSK also supplies the Pilot oil pressure (Pp) for the PVE to activate the spool (PVBS). Specialdesigned float spools also allow oil flow in both directions between A- and B-port not opening to pumpnor tank.

When looking at the figure you see the valve section from PVP towards PVS with the PVM and PVEstandard mounted. When PVM and PVE are interchanged it’s called option mounted.

Oil out of A-port = PVM pushed towards PVB = retract = LVDT moves into PVE.

With the spool in neutral, default position when held by the neutral spring, the connection to theapplication via ports is blocked. Moving the PVBS towards the PVE, as in the figure, opens a connectionbetween P and A and also between B and T. This is done by either pushing the PVM or activating the PVE.The PVE moves the PVBS by letting Pilot Oil Pressure (Pp) push on the right end of the PVBS and releasingpressure from the left end. For details on PVG 32 please see PVG 32 Proportional Valve Groups, TechnicalInformation, 520L0334.

PVE functionality

This section has focus on how the PVE works and interacts. The description here is general and variantspecific descriptions will all refer to this.

The PVE is an electro mechanical device, meaning that functionality is depending on mechanical,hydraulic, electrical and control conditions given by PVE, PVG, application and vehicle. The result of this isthat implementing operation and safety conditions also must include vehicle specific considerations.

Hydraulic subsystems

The hydraulic subsystem is used for moving the spool and thereby open the valve for work flow.

Electronics

The hydraulic subsystem moves the spool and thereby opens the valve for work flow. The heart in thehydraulic subsystem is the solenoid valve bridge which controls the Pilot Pressure (Pp) on spool ends. Itconsist of four poppet valves, the two upper are normally closed (NC) and the two lower are normallyopen (NO).

The Pp will work against the PVBS neutral spring when the spool is moved out of blocked (neutral) andtogether with the spring when going in blocked. This combined with a larger opening in the NO than inthe NC will give a faster movement towards blocked than out of blocked.

When the PVE is powered the solenoids are all put in closed state. To move the PVBS to the right NC1 andNO4 are opened and NC3 and NO4 are kept closed.

The activation of the solenoid valves represents oil consumption and thereby also a pressure drop in thepilot oil gallery. By simultaneous use of multiple PVE the Pp can fall and result in performance problems.

The two check valves next to the NO are anti-cavitation valves. The orifice to tank reduces tank pressurespikes and can also be used for ramp function.

W WarningObstacles for the Pilot oil pressure (Pp) can have direct influence on spool control. Reduced Pp will limitspool control. Too high Pp can harm the PVE.

Variant of hydraulic subsystem: PVEA

Hydraulic variant: PVEA

NO2 and NO4 are replaced with orifices.

W WarningPVEA is not for use on PVG 100.

Variant of hydraulic subsystem: PVHC

The PVHC does not work as a PVE and does not have transducer, anti cavitation nor protection againsttank pressure spikes. It is necessary to use the PVHC in combination with 25 bar [362.6 psi] pilot pressure,and standard FC spools fitted for hydraulic actuation. Because of the 25 bar pilot pressure, it is notpossible to combine PVHC with PVE on a PVG.

Hydraulic subsystem variant: PVHC

With electrical proportional actuation, the main spool position is adjusted so that its position correspondsto an electrical control signal. The control signal is converted into a hydraulic pressure signal that movesthe main spool in the PVG. This is done by means of two proportional pressure-reducing valves. Theelectrical actuator can be controlled either by a current amplifier card, or directly from a programmablemicro-controller.

Mechanical subsystem

The mechanical subsystem gives interface to valve and control system and provides protection tohydraulic and electrical/electronic subsystem. The LVDT, not used on all variants, gives feed back toelectronics on spool position. The LVDT is calibrated in production and recalibration should only be donein special cases. The standard PVE has an aluminum block for distributing pilot oil. PVE with anodizedblock are available.

The connector gives the electrical interface to power and control system. Danfoss have a variety ofconnectors. We know that tradition and the aspects of serviceability are important when our customerschoose. We have chosen the Deutsch connector as our main solution. The quality of wiring has directinfluence on water integrity and signal quality therefore disturbance or changes in cabling can influencesafety and performance.

PVE connectors: Hirschmann/DIN, AMP and Deutsch

Electronic subsystem

The PVE (A/ H/ M/ S/ U) control signal is a low current voltage, a PWM can also be used. The PVEP hasbuild-in a PWM evaluation and cannot be controlled by proportional voltage. The control signal isreferred to as US.

The PVE features Closed Loop Control (CLC). This is made possible by on board electronics and anintegrated feedback transducer that measures spool movement. The integrated electronics compensatefor flow forces on the spool, internal leakage, changes in oil viscosity, pilot pressure, etc. This results inlower hysteresis and better resolution.

In principle the set-point determines the level of pilot pressure which moves the main spool. The positionof the main spool is sensed in the LVDT which generates an electric feed-back signal registered by theelectronics. The variation between the set-point signal and feed-back signal actuates the solenoid valves.The solenoid valves are actuated so that hydraulic pilot pressure drives the main spool into the correctposition.

The LVDT (Linear Variable Differential Transducer) is an inductive transducer with very highresolution. When the LVDT is moved by the main spool a voltage is induced proportional to the spoolposition. The use of LVDT gives contact-free connection between mechanics and electronics. This meansan extra long lifetime and no limitation as regards the type of hydraulic fluid used.

The PVEO and PVHC do not have embedded control electronics and do not support closed loop control.

The choice of PVE also decides the level of feedback and safety. PVE are available with fault monitoring,spool direction indication, spool position feedback and separate float control.

The fault monitoring is available in PVEA/H/S/P/U and is a utilization of the ASIC.

Direction Indication is available in PVEO/A/H and they are dual powered PVE where separate pins give anactive feedback for spool movement.

Spool position is available in PVES and is a precise feedback on a separate pin for actual spool position.

The separate float control is a protection against unintended float activation.

The PVEM, PVEO and PVHC do not have fault monitoring.

Fault monitoring and reaction

The fault monitoring system is available in two versions:

• Active fault monitoring provides a warning signal and deactivates the solenoid valves. A reboot of thePVE is required to reactivate.

• Passive fault monitoring provides a warning signal only. A reboot is not required.

Both active and passive fault monitoring systems are triggered by the same four main events:

1. Control signal monitoring

The Control signal voltage (US) is continuously monitored. The permissible range is between 15% and85% of the supply voltage. Outside this range the section will switch into an error state. Adisconnected US pin (floating) is recognized as neutral set point.

2. Transducer supervision

The internal LVDT wires are monitored. If the signals are interrupted or short-circuited, the PVE willswitch into an error state.

3. Supervision of spool position

The actual position must always correspond to the demanded position (US). If the actual spoolposition is further out from neutral than the demanded spool position (>12%, PVEA: >25%) or inopposite direction, the PVE will switch into an error state. With neutral/blocked setpoint the toleranceis +- 0,5 mm relative the calibrated neutral position. Spool position closer to neutral and in samedirection will not cause an error state. The situation is considered “in control”.

4. Float monitoring

Float must be entered or left within a time limit. On the six pin float PVE too high delay will cause anerror state. The float Time Outs has own thresholds. Only relevant for the six pin PVEH-F.

Active fault reaction is activated after 500 ms of error (PVEA: 750 ms).

• The solenoid valve bridge is disabled and the PVBS is released to spring control

• The error pin is powered*

• The LED change color

• The state is memorized and continues until PVE reboot

Passive fault reaction is activated after 250 ms of error (PVEA: 750 ms)

• The solenoid valve bridge is NOT disabled and the PVBS is NOT released

• The error pin is powered ( for PVE with direction indication both DI pins goes low by fault.)

• The LED change color

• The state is active for minimum 100 ms and is reset when error disappears

W WarningError pins from more PVEs may not be interconnected. Not activated error pins are connected to groundand will disable any active signal. Error pins are signal pins and can only supply very limited powerconsumption.

To avoid the electronics in undefined state a general supervision of power supply (UDC) and internal clockfrequency is implemented. This function applies to PVEA, PVEH, PVEP, PVES and PVEU independently offault monitoring version and PVEM - and will not activate fault monitoring.

The solenoid valves are disabled when:

• the supply voltage exceeds 36 V

• the supply voltage falls below 8.5 V

• the internal clock frequency fails

Direction indication feedback (-DI)

PVE with build in indication for spool movement direction are available.

The PVE–DI has dual power supply. UDC1 only supplies solenoid valves. UDC2 supplies electronics and feedback. The PVE does not work without UDC2. DI-A and DI-B are relative standard mounting. The inputsignal fault monitoring is disabled if UDC1 is disabled. DI-A and DI-B are relative standard mounting.

The DI has two direction feeedback signals with output high (close to UDC) when the spool is in neutralposition. If the spool moves out of neutral position, the direction signal switches to low (< 0.2 V). One ofthe signals goes low by spool ~0,8 mm out of neutral and high by spool within 0,4 mm out of neutral.

Solenoid disabling function (-NP)

PVEH-NP and PVEA-NP have a build in feature that disables the solenoids by US at 50% and gives afeedback on the solenoid status. This is done to facilitate application monitoring. The fault monitoring isstill activated but the closed loop will remain passive until the control signal shifts.

US disable range 48 % UDC to 52 % UDC

Building in safety

All brands and all types of control valves (incl. proportional valves) can fail. Thus the necessary protectionagainst the serious consequences of function failure should always be built into the system. For eachapplication an assessment should be made for the consequences of pressure failure and uncontrolled orblocked movements.

To determine the degree of protection that is required to be built into the application, system tools suchan FMEA (Failure Mode and Effect Analysis) and Hazard and Risk Analysis can be used.

FMEA (Failure Mode and Effect Analysis) IEC EN 61508

FMEA is a tool used for analyzing potential risks. This analytical technique is utilized to define, identify,and prioritize the elimination or reduction of known and/or potential failures from a given system beforeit is released for production. Please refer to IEC FMEA Standard 61508.

Hazard and risk analysis ISO 12100-1 / 14121

This analysis is a tool used in new applications as it will indicate whether there are special safetyconsiderations to be meet according to the machine directives EN 13849. Dependent on the determinedlevels conformety this analysis will detirmine if any extra requirements for the product design,development process, production process or maintenance, i.e. the complete product life cycle.

W WarningAll brands and all types of directional control valves – including proportional valves – can fail and causeserious damage. It is therefore important to analyze all aspects of the application. Because theproportional valves are used in many different operation conditions and applications, the machinebuilder/ system integrator alone is responsible for making the final selection of the products – andassuring that all performance, safety and Warning requirements of the application are met.

• The PVE is controlled with a low current voltage signal.

• The spool stroke is proportional to the control voltage (US).

• The power is supplied via the supply wire (UBAT or UDC).

• The ratio US/UDC defines the actuation. For PVEU a defined voltage.

• A not connected US pin (floating) is recognized as US = ½ UDC.

PVEO

PVE ON/OFF activation

The PVEO has two independent powered sets of solenoids. By powering a set of pins the actuator isactivated. By standard mounted PVE the A set gives full flow on A port and B gives on B port. Bothdirections activated at same time will keep the spool in neutral.

PVEO schematic and characteristic

W WarningThe PVEO is designed to have UDC=12 V or UDC=24 V.The solenoids might be activated by voltage down to 6 V.

PVE for float spool

Danfoss has developed two PVE variants to support the float spool. The float spool is a 4/4 spool, whereas the standard is a 4/3 spool giving another characteristic and maximum stroke. These variations arecovered by the built-in electronics. PVE for float spools are not designed for standard 4/3 spools.

There are two variants of float spool PVBS.

• Float A – 0,8 mm dead band, max flow at 5,5 mm. Float at A = 8 mm, from 6,2 mm partial float.

(PVEH-F with six pin connector gives protection against entering float by using low Us. The floatsignal has priority to the Us in the PVEH-F six pin.)

• Float B – 1,5 mm dead band, max flow at 4,8 mm. Float at B = 8 mm, from 6 mm partial float.

(PVEM-F and PVEH-F with four pin connectors give no built-in protection against entering float.)

PVHC current response and hysteresis @ 25 bar Pp, 21 ctS, 25 °C. The PVHC control is done by dual PulseWidth Modulated (PVM) high current supply 100-400 Hz PWM control signals.

The PVHC does not have fault monitoring and internal closed loop control of the spool.

The PVHC has high hysteresis. The hysteresis is affected by viscosity, friction, flow forces, dither frequencyand modulation frequency.

The spool position will shift when conditions are changed e.g. temperature change.

For PVG controlled by PVHC hysteresis is influenced by lever (PVM).

PVE hysteresis

The controllability of the PVE depends on the solenoid valve bridge and the electronic capacity of themodule. Hysteresis is a measurement on spool position precision and repeatability. Hysteresis is not adescription of position maintaining.

PVE warnings

W WarningNot applying to the Operational Conditions can compromise safety.All brands and all types of directional control valves – including proportional valves – can fail and causeserious damage. It is therefore important to analyze all aspects of the application. Because theproportional valves are used in many different operation conditions and applications, the machinebuilder/ system integrator alone is responsible for making the final selection of the products – andassuring that all performance, safety and Warning requirements of the application are met.A PVG with PVE can only perform according to description if conditions in this Technical Information aremet.In particularly exposed applications, protection in the form of a shield is recommended.When the PVE is in fault mode the quality of performance and validity of feedback is limited dependingon the fault type.Error pins from more PVEs may not be connected. Inactive error pins are connected to ground and willdisable any active signal. Error pins are signal pins and can only supply very limited power consumption.Deviation from recommended torque when mounting parts can harm performance and module.Adjustment of the position transducer (LVDT) will influence calibration, and thereby also safety andperformance.When replacing the PVE, the electrical and the hydraulic systems must be turned off and the oil pressurereleased.PVEA is not for use on PVG 100.Hydraulic oil can cause both environmental damage and personal injury.Module replacement can introduce contamination and errors to the system. It is important to keep thework area clean and components should be handled with care.After replacement of modules or cables wiring quality must be verified by a performance test.By actuation at voltage below nominal PVG will have reduced performance.The PVE is not designed for use with voltage outside nominal.Obstacles for the Pilot oil can have direct influence on spool control.Reduced pilot oil pressure will limit spool control.Too high pilot oil pressure can harm the PVE.
